The rotifer Conochilus hippocrepis in a movie

Post by myriophyllum »

Hi,

some weeks ago, I went to a small lake in a forest, that used to have over the
last years fine colonies of Volvox aureus in it.
This time it was a great surprise to find not just them, but some of the most
beautiful rotifers, too!
They belong to the species Conochilus hippocrepis and their colonies move freely
in the water just like Volvox does.
I've newer seen before both rotating guys in the same water...

In this Video you can see some scenes in darkfield and bluish Rheinberg illumination:

(Zeiss Standard 18; objectives 6,3/0,40; 10/0,32; 25/0,8; 25/0,65; 40/0,95;
Zeiss Ultrakondensor und turret condensor (top lenses Achr.-Apl. 1.4 or Apl. 0.9)


Finally some stills:

Your comments are welcome.

Jens,

I found these only one time eight years ago when i was just just starting to play around with a microscope.

Along with Volvox, they remain at the top of my list for subjects that are amazing to see in motion (and darkfield!), so I really enjoyed seeing the video.

Hi Charles,

yes, spherical subjects are very fascinating to me too
and these are just great. :-)

Good luck finding some Conochilus by yourself.

Greetings

Jens

Superb videos. I didn't realize the zeiss ultracondenser works with low power (6x) objectives. Perfect black background.

Hi Curt,

no, the 6.3 objective was used with the turret condenser (Achr. apl. 1.4 with 0.9 top lens).
It is not easy to use the ultracondenser with an objective 10...
